AXEL EDVARD JOHANSSON, OF STOCKHOLM, SWEDEN.

LUBRICATING MEANS FOR CENTRIFUGAL SEPARATORS AND THE LIKE.

Specification of Letters Patent.

Patented Aug. 24, 19115.

Application filed February 25, 1915. Serial No. 10,618.

To all whom it may concern:

Be it known that I, AXEL EDVARD JoHANs- SON, a subject of the King of Sweden, residing at Stockholm, in the Kingdom of Sweden, have invented new and useful Immeans for centrifugal separators and thelike, in which lubricating oil is contained in the casing for the gears and the movable parts cooperating therewith, in such manner that the oil is always in contact with some of these parts and is transmitted and supplied to the others when the driving gears are operated. A driving means of this kind as embodied in manually operated centrifugal separators is ordinarily so constructed that to one side of the spindle of the separator reaching down into the inclosed casing the shaft of the driving gear is journaled, which gear by means of a pinion coacts with and drives a worm gear journaled on the other side of the spindle and engaging the same. It being important that the part of the spindle reaching into the casing be as short as possible, the worm gear is journaled considerably higher up in the casing than the driving gear. The latter gear having to carry the oil up to the worm gear, the result will be that owing to a considerable quantity of oil running 055' the driving gear, a suthcient quantity of oil will not reach the worm gear which will thus not be enough lubricated. This disadvantage is eliminated by my invention which is broadly characterized by that below the gear journaled higher up in the casing an additional receptacle for oil is provided in which receptacle the said gear reaches down. Tn this receptacle all the lubricating oil may collect which during the operation of the apparatus is splashed or thrown from the driving means, and when the driving gears have been in operation for only a short while the additional receptacle will be filled and will be kept filled so that the worm gear will run in oil.

In the accompanying drawing T have shown an embodiment of my invention by way of example.

Figure 1 shows a sectional side view of the apparatus, Fig. 2 shows asectional end view, and Fig. 3 shows a sectional plan view of the same.

Referring to the drawing, 1 is the inclosed.

vided with the worm 2 reaches down. The

worm gear 4 engages with the worm 2 and is secured to the shaft 5 as is also the pinion 6 wh1ch engages the driving gear 7 secured on the crank-shaft 8 of the separator. The crank-shaft 8 is 'journaled on the opposite side of the spindle 3 from the shaft 5 and considerably lower than this. The lower portion of the driving gear 7 reaches down inan oil receptacle 9. When the gear 7 is rotated in usual manner in the direction indicated by the arrow 10, the oil will be brought along by the gear wheel. A great quantity of the oil will fiow from the wheel back into the receptacle 9, while the remainder of the oil brought along by the wheel will be supplied to the pinion 6. The

oil on the pinion is splashed and thrown off and is collected in an additional receptacle 12, which I provide below the worm gear a and the'pinion 6. This receptacle 12 is soon filled and the worm gear will thereafter run in oil continually, which oil will thus be supplied to the worm by the worm gear in sufiicient quantities.

As evident from Fig. 2 of the drawing the oil receptacle 9 for the driving gear 7 is placed at one side of the casing. By this arrangement the bearing 13 for the spindle will be easily accessible from below and through an opening 14: in one side of the casing 1. The bottom between said wall and the receptacle 9 is preferably utilized as bottom of the additional receptacle for the worm gear 4. i

My invention is also advantageous in that it does not in any manner necessitate a change or enlargement of the casing l inclosing the driving means.

T claim:

1. In a lubricating means for centrifugal separators and the like, the combination of a casing, a driving gear journaled in said casing, a receptacle for oil in said casing located so the driving gear reaches into the same, a worm gear driven by said driving gear and journaled in the casing, and an additional receptacle for oil located in the casing below the worm gear so that the worm gear reaches into the same and so that oil brought along by the driving gearwill be collected in the same, substantially as and for the purpose set forth.

- 2. In a lubricating means for centrifugal separators and the like, the combination of a casing, a driving gear located at one side of the casing and journaled in the same, a receptacle for oil located at one side of the casing below the driving gear so that this gear reaches into the same, a Worm spindle, a Worm gear engaging said spindle and driven by said driving gear and journaled in the casing, an additional receptacle for oil located in the casing below the Worm gear so that this gear reaches into the same and so that oil brought along by the driving gear will. be collected in the same, a

- bottom between the Wall of the casing and the receptacle serving as bottom of the additional receptacle, and a bearing in said bottom for the spindle, substantially as and for the purpose set forth.
